SASH-LIFTER.

SPECIFICATION forming part of Letters latent No. 670,956, dated April 2,1901. Application filed November 20, 1900. Serial No. 87,120. (Nomodel.)

To all whom, it may concern:

Be it known that I, PERCY PETER HOUGH- TON, a citizen of the UnitedStates, residing at Seabright, in the county of Monmouth and State ofNew Jersey, haveinvented a new and useful- Sash-Lifter, of which thefollowing is a specification.

This invention relates to improvements in devices for operatingwindow-sashes; and the object is to providea simple and improvedconstruction by means of which windowsashes or ventilators may bequickly and conveniently opened or closed.

With the above object in view the invention consists in the novelfeatures of construction hereinafter fully described, particularlypointed out in the claims, and clearly illustrated by the accompanyingdrawings, in which Figure 1 is a side elevation of a device embodying myinvention; Fig. 2, a top plan view, partly in section; Fig. 3, atransverse section on the line 3 3 of Fig. 1; Fig. 4, a sectional viewof a modification, and Fig. 5 a similar view of another modification.

Referring now more particularly to the accompanying drawings, Adesignates a hanger secured at some convenient point adjacent to thewindow-sash or ventilator to be operated. Mounted in said hanger andextending transversely thereof is a shaft B, having fixed thereon on oneside of the hanger an eccentrio 0, and a gear D secured thereon by asetscrew E on the opposite side of said hanger. Mounted in said hangeris a short shaft F, having a gear G, meshing with gear D and provided atits outer end with a sliding handle H. This shaft is rotatably retainedin said hanger by set-screwI, engaging in an annular groove J, formedtherein.

K designates four guide-rails so spaced as to receive the eccentric andits shaft therebetween, the eccentric extending longitudinally and theshaft transversely thereof, the guide-rails being freely movable backand forth. Said rails are secured together and spaced the properdistance at their forward ends by a block L, in which the inner end ofan operating-rod M is threaded. At their opposite ends the rails aresecured together and spaced by plates N. These plates are connectedcentrally by a pin 0, which pin extends through an eccentric slot,formed in the eccentric. Mounted between the guide rails at their rearends is a pulley Q, in contact with the periphery of the eccentric andhaving its axis supported by plates N.

Suitably mounted adjacent to the sash to be operated is a pulley R,around which a wire cable is passed, the cable being crossed 63 and atits ends extended in opposite directions and secured to theoperating-rod by clamps S. The cable is also secured to the pulley by agrip T, countersunk into the face of the pulley. The inner end of thecable 65 passes over a pulley U, mounted adjacent to the hanger, andcarries a counterweight V.

Secured to the shaft of the pulley R is an arm or lever W. Pivoted tothe outer end of said lever is an arm X, which is attached to theventilator or sash Y. The operatingrod might be directly connected withthe sash by an arm a, as illustrated by dotted lines in Fig. 1.

The operation of my invention Will be readily understood, it beingsuflicient to state that by moving the eccentric upon its axis throughthe medium of the handle and gear the operating'rod is moved in eitherdirection,according to the direction of the rotation of the ec- 8ocentric, and the sash opened or closed. The eccentric is locked inposition holding the sash open or closed by frictional contact with thepulley.

In the modification illustrated in Fig. {L the axis 1) of the eccentricc is formed as a part of the hanger cl, the eccentric being providedwith a hub e, to which the hub f of a gear 9 is secured, said gearmeshing with a gear h on the inner end of a shaft i, mounted in an armj, secured to the axis formed upon the hanger.

In the modification illustrated in Fig. 5 the gears are dispensed withand the eccentric 70 mounted upon a shaftl,supported by a hanger 5 m andhaving on its outer end a sliding handle n.

Having thus fully described myinvention, what I claim as new, and desireto secure by Letters Patent of the United States, is-

1. In a device of thecharacter described, the combination with areciprocable operating-rod havinga projection and provided with arotatably-mounted disk, of an eccentric Li ia 670,9 56

m onnted independently of the rod,and formed with a slot receiving saidprojection and having its periphery in contact with said disk, and meansfor operating the eccentric, substantially as described.

2. In a device of the character described, the combination with areciprocable operating-rod carrying a projection, of an eccentricmounted independently of the operating-rod and formed with a slotreceiving said projection, a gear carried by the axis of said eccentric,a short shaft mounted adjacent to said eccentric and carrying a gearmeshing with said firstmentioned gear, and a handle carried by saidshort shaft, substantially as described.

3. In device of the character described, the combination with areciprocable operating-rod carrying spaced guide-rails, of an eccentricmounted independently of said rod and movable between said rails andformed with a slot, means for rocking said eccentric,

a pin carried by the guide-rails and projecting into said slot of theeccentric, and a disk mounted between the guide-rails and normallyengaging the periphery of the eccentric, substantially as described.

4. The combination with a swinging sash, of a reciprocable operatingrod, a pulley mounted independently of said rod, a cable passing aroundsaid pulley and secured to said rod, an operative connection between theshaft of said pulley and the sash, and means for reciprocating the rod,substantially as described.

5. The combination with a swinging sash, of a reciprocable rod, a pulleymounted inde' pendently of said rod, a cable passing around said pulleyand having its ends crossed and its oppositely-extending portionssecured to said rod, a balance-weight carried by one end of said cable,an operative connection between the shaft of said pulley and the sash,and means for reciprocating said rod, substantially as described.

6. The combination with a swinging sash, of a reciprocable rod, aneccentric mounted independently of the rod and reciprocating the same,means for rocking the eccentric, a pulley mounted independently of therod, a cable passed around said pulley with its ends extending inopposite directions with the oppositely-extending portions secured tothe rod, and an operative connection between the shaft of said pulleyand the sash, substantially as described.
